Product Description

Zylkene is a non-drowsy supplement to help ease situational stress and environmentally-induced problems that are commonly seen in dogs and cats. Zylkene helps balance reactions in some situations (travel, moving, adoption, grooming, meeting new people, loud noises, etc.) and helps animals maintain normal and relaxed dispositions. Zylkene may also open pets’ receptivity to behavior-modification training.

Zylkene uses alpha-casozepine, a natural ingredient found in cow’s milk, to help balance the stress reactions of dogs and cats safely and with no tranquilizing or sedating effects. Milk-sourced alpha-casozepine is known to promote relaxation in babies, and it works in a similar way for your pet, providing a sense of comfort and contentment to help them cope with stress or adapt to new situations. It’s perfect for most pet stressors like loud noises, visits to the vet or groomer, as well as unfamiliar people and places. Plus, it’s free of lactose and preservatives, making it ideal for sensitive tummies.


  • Clinically proven to help relieve stress without the drowsy side effects
  • Vet recommended to help relieve anxiety during thunderstorms, car rides, separation and more
  • Made with natural ingredients that are easy on sensitive stomachs
  • Taste tested and proven effective
  • For best results, start giving Zylkene 1-2 days before a stress event. For short and long term use
